Following the events of the previous episode, Taverner (Kristin Scott Thomas) attempts to frame Jackson Lamb (Gary Oldman) and the Slough House team for the botched kidnapping operation that has now turned into a public relations nightmare and a potential bloodbath.
Her cold, calculating nature is fully exposed as she prioritizes her career over the lives of the agents and the hostage.
River begins to step out of his grandfather’s shadow, proving he has the instincts of a top-tier field agent.
River Cartwright (Jack Lowden) uses his skills to track down the truth behind the kidnappers and their connection to Taverner. He discovers that the entire kidnapping was a "false flag" operation gone wrong, intended to boost MI5’s profile by "saving" the victim at the last second.
